Abstract (en)
[origin: US2007165561A1] When the binding of a mobile station (MS) in a home agent (HA) expires, the HA generates an identifier from the MS's IMSI. The HA maintains a binding between the home address (HoA) and a special care of address (MAP-CoA), where the host ID of MAP-CoA is the identifier, and where the network ID of MAP-CoA is a special code. When a packet destined for the HoA is received at the HA, the HA responds by communicating the MAP-CoA to the PDSN that serves the special code. The PDSN recovers the IMSI from the host ID of the MAP-CoA, and uses the IMSI to page the MS. The MS responds by setting up a call, obtaining a new care of address, and then binding the new care of address with its HoA in the HA. Advantageously, packets can be sent to a dormant MS at its HoA without out-of-band signaling.
